This is only getting weirder every time I try something else. A complete purge and re-install has resulted in no resolv.conf at all in the /etc directory. It's now a symbolic link to /var/run/NetworkManager/resolv.conf but is still controlled by dnssec-triggerd. I don't know if it has the immutable attribute. It gives an error message when I try to check it. At least this time the DNS does work. Maybe the re-install forced it to update to the current master sig/key?

Meanwhile, another system that I hadn't gotten to still has /etc/resolv.conf and it has the immutable attribute. But this one is still successfully producing DNS lookups. Since it works, I won't mess with it for now. If I can ever get a handle on some sort of consistent behavior I'll see about a new thread.

Please open a new thread for this problem, thanks.

I am absolutely sure that the dnssec-trigger package from Devuan does not set /etc/resolv.conf immutable so please include details of how you installed it and also the full output of apt policy in the new OP.

Well, on my systems (all of them now) is locks resolv.conf and fails to provide the DNS lookups that it has forced the system to ask it for. I've now removed it from all of my systems. It worked for a few days and then went haywire. Frustrating. Hasn't there been a recent update of the "master" signing key? Could that have broken it?

Well I've just tried installing the dnssec-trigger package in the Devuan ASCII live environment and it did not set resolv.conf immutable, I was able to alter and delete the file afterwards with the usual root permissions.

Maybe Devan would not, but the dnssec-trigger package comes from nlnet labs, and they would:

https://www.nlnetlabs.nl/projects/dnssec-trigger/about/

There used to be a race condition between dnssec-trigger and the system but this was fixed in 0.6, with a 'system preferences' override on OSX and Windows, and chattr immutable on Linux and BSD.

You must have blindly copy&pasted some forum suggestion, no De??an package would use such an awful hack.

You should probably open a new thread for that problem, dnssec-trigger & unbound should work just fine.

No, I didn't even know the immutable attribute existed until I figured out how to remove it. Something else set it. And that was a peripheral problem. The real problem is that dnssec-trigger doesn't work anymore. DNS info is not looked up and the machine cannot use the network with it installed. Something in the batch of updates I downloaded broke it.

Sorry for the trouble, I presumed you had tested the new kernel before attempting to remove the old versions.

Use apt to re-install the old kernel versions:

cd /var/cache/apt/archives
sudo apt install ./name_of_old_kernel_version.deb

^ That will downgrade automatically.

You did that yourself, Devuan ASCII doesn't have dnssec-trigger installed by default and /etc/resolv.conf is not set immutable.

That would install all of the kernels in the directory. Sounds messy.

Fortunately, after some more struggles I figured out what was wrong. The resolv.conf file was set read-only even for root, and contained only 127.0.0.1 as the nameserver. Well, whatever was in those latest updates broke dnssec-trigger. I don't know enough about it to say what exactly went wrong. When unbound stopped working, it prevented any network access from working since all applications would think that 127.0.0.1 was the place to request DNS information. When I finally figured out how to free resolv.conf (it was a completely different file control system than chmod, something I've never heard of before "chattr") it returned to the control of network manager and the system is usable again.

So now it looks like dnssec-trigger is not safe to use since these updates broke it. I'll have to remove it from all my systems and continue trying to figure out how to setup unbound independently.

Alright, I give up. Since I don't have access to the network anymore, I can't get the files I deleted to try again. Looks like I have no option but a complete re-install when I have some time. This is the first time I have had such a debacle with Linux. But if I re-install and updating breaks my networking again, what then?

Re: TWO kernels in one update?

dummy@example.com (Micronaut) — Thu, 13 Feb 2020 22:30:07 +0000

All I have to do is reboot into Windows and there are no network problems. Something in the Linux updates broke my networking. Which is really shocking. Bad updates are supposed to be a Windows thing...

Well, I just recently had a case with my wifes desktop where also the network stopped working, the onBoard Realtek chip went bad. Indication was that the usual lights for speed and activity did no more work.

I put in EE1000 card I had laying around, and the network was up again.

Consider such a scenario.

Good luck, rolfie

The system having the problems is a desktop, no wifi involved. I simply downloaded updates using the above sources.list, "aptitude update" and then "aptitude safe-upgrade" and the network stopped working. The log posted above is all of the packages installed by that update. Looks like a lot of CUPS updates. But the only thing I can figure has anything to do with network access is the kernel. Hmm...

Got two PC running ASCII with backports kernel 4.19.6, 4.9.12 also is installed as backup, no network issues since the ASCII installation about two years ago. I have wired GBit lan here. Basically the same sources.list entries here.

What exactly is your setup? Wifi? Can you try wired network?
